3.20 Ct. Blue Sapphire from Ceylon (Sri Lanka)

There is a story behind every gem that arrives at our bench, and this C.Dunaigre certified Blue 3.20 carat oval shape blue sapphire is no exception. Born in the fabled soils of Ceylon Sri Lanka, this sapphire began its life as a concentrated whisper of color in ancient alluvial gravels, carried by rivers and polished by time. The stone measures 9.44 by 7.51 by 5.39 millimeters, and it wears a mixed brilliant cut that balances scintillation and depth. Evaluated as eye clean at eye level, with intense color intensity and an excellent polish, this sapphire has also been heat treated to stabilize and enhance its tone. At The Natural Sapphire Company we catalogue each gem not only by its measurements and grades, but by the journey it has made from the earth to your hand, and by the human hands that shaped it into a jewel of enduring presence.

The landscape of Ceylon has long been entwined with the lore of sapphires, and the communities who mine and trade these stones carry centuries of craft knowledge. Small scale miners seek pockets of corundum in riverbeds and old stream gravels, and their finds are evaluated by experienced eyes before any stone is chosen for cutting. This particular sapphire passed through those local hands, and thereafter through meticulous sorting and certification, before the cutter took its rough form and began to reveal the blue within. The certification by C.Dunaigre offers assurance about origin and treatment, and it ties this gem to a lineage of Ceylon sapphires that have adorned crowns and sacred objects, and that have been prized for both their beauty and their connection to place. When you hold this sapphire, you hold a piece of that history, a gem that has survived geological time and human selection to become an object of intention.

On the lapidary bench the cutter faced the classic choices between size and brilliance, between color saturation and light return. The chosen oval outline and mixed brilliant faceting reflect a deliberate compromise designed to maximize the stone s vivid blue while allowing lively scintillation across the table. The crown facets disperse and scatter light, while the pavilion facets act as a mirror to return that light through the face of the stone. The result is a sapphire that appears to glow from within, its intense color remaining steady, while flashes of lighter blue and violet play across the surface as the stone moves. The excellent polish ensures that those flashes are clean edged and bright, and the eye clean clarity grade means that the surface and internal features are free of visible distractions at typical viewing distances, allowing the color and cut to be the focal points of attention.

What sets this sapphire s sparkle apart is the very way corundum is built, and the way the cutter has honored that structure. Corundum crystallizes in a trigonal lattice of aluminum and oxygen, producing a hard and dense material that refracts and reflects light with a purity few gemstones can match. The refractive behavior of sapphire means that light entering the gem is both bent and guided, creating multiple internal reflections that ultimately escape through the crown as the bright flashes you perceive as sparkle. In blue sapphires there is also a strong pleochroism, a directional variation in color, so that different facet orientations reveal slightly different blues as the gem turns. The mixed brilliant cut leverages this trait by orienting facets to capture and alternately reveal those color shifts, creating a dynamic effect that seems to change with every angle. Heat treatment has been applied to enhance the stone s color and clarity in a manner that is stable and permanent, and combined with the cutter s exacting facet geometry and the stone s inherent optical properties, the result is a scintillation and depth that feels both lively and profoundly modern.

This sapphire is ready to become a central story in your jewelry, whether set as a solitaire ring for daily admiration, placed in a pendant to catch light by the throat, or held within a bespoke creation that frames its intense Ceylon blue. The oval shape and weight of 3.20 carats provide a presence on the hand that is elegant and unmistakable, and the photographs showing the stone on a finger hint at how it sits with poise and proportion.
